mortality decreases or fecundity increases with density of predator or prey it can lead to destablizing effects. If subject to inverse density-dependence, i.e. How does individual behavior affect population dynamics?įor example, if both predator and prey are subject to density-dependent increases in mortality or decreases in fecundity, this will tend to regulate population size leading to stability. Secondly, investigating the behavior of predators can tell us how predators influence the population dynamics of both predator and prey. This line of investigation leads to models predicting "Optimal foraging" Understanding the ecology of predators can help us to understand the evolution of their behavior when we examine it in the context of the prey environment.
